Post like a studio.
Run like a script.
Castn turns what's already working into publish-ready slideshows and UGC video — captured once, produced on repeat, shipped straight to TikTok.
Built for pages
that post daily
One captured format, running on its own.
Turn one brief into a
week of posts
Slideshows and talking-head video come out of the same pipeline — per-slide control when you want it, hands off when you don't.
Slideshow engine
Every slide gets its own prompt, caption, and retry. Nothing is a black box you have to accept whole.
Capture what's working.
Run it forever.
Point Castn at a post that landed. It reads the structure — slide roles, framing, pacing — and keeps it as a spec you can apply to anything.
Format LibraryNEW
A shelf of structures that already earned their views, each one a click away from a fresh product.
Straight to TikTok,
at full quality
Files upload as bytes rather than being re-fetched and re-encoded, so what you approved is what publishes.
Queue & publish
Line up a week in one sitting across every page you run. Publish live, or land in TikTok drafts for a phone-side look first.
The realism pass
Sensor grain, flattened colour, a little handheld drift — so it reads as filmed, not rendered.
Every account, one queue
Run as many pages as you like side by side — connected once, then published to without cross-wiring their voice or stats.
Know which format
actually earned it
Results land back against the format that produced them, so the library sorts itself by what performed rather than what felt good.
Per-format results
Views, likes and shares tied to the structure behind them, across every account.
Trending signals
Product and format movement surfaced early, scored, and dropped straight into the next brief.
Set it up once.
It runs without you.
- 01
Capture a format
Drop in a link, or build one from scratch. Castn stores the skeleton — not the pixels — so it can rebuild it endlessly.
- 02
Connect your accounts
Link the TikTok pages you run. Castn publishes on your behalf and keeps every account's results separate.
- 03
Let it post
New posts get produced, finished, and pushed on the cadence you set. You check analytics, not render queues.
Everything the loop needs
No bolt-on integrations to babysit. Generation, finishing, publishing, and measurement share one pipeline.
Format Library
A living shelf of structures that worked. Apply any one to a new product in a click.
Character packs
Lock a face across angles so a page keeps one consistent presenter, post after post.
The realism pass
Grain, flattened colour, and handheld drift applied on the way out — so it reads as filmed.
Continuation chains
Extend a clip segment by segment, each one starting from the last frame of the last.
Scheduling
Queue a week in a sitting. Publish live, or land in TikTok drafts for a phone-side look.
Trending signals
Product and format movement surfaced early, scored, and dropped into the brief.
Multi-account
Run many pages side by side without cross-contaminating voice, cadence, or stats.
Model choice
Swap the image or video model per template as the frontier moves. No rewrite required.
